I don't toe the liberal line on this one
Some companies will use more transparent accounting than others, with or without government interference. Investors need to use their heads accordingly, and they will given enough bad experience.
Some governmental interference is necessary to make sure economic information is available, but where a choice in the market exists today (between companies that do and do not account for options), I'm not sure that the government should interfere.
Government should have a redistributionist role, but it should play very carefully when it tries to control actual market operations.
